What if 1930s Grand Prix cars had Wings? - Assetto Corsa Experiment

[@DimZ_F1]

It would be interesting to see the Type C with the wing, plus modern tyres and modern brakes. And maybe we could get to see what that beast will accomplish against moderns cars in a modern track?

Winged sprint cars: "Am I a joke to you?"

[@jcgabriel1569]

My thoughts on the subject is this: I think they would benefit from wings, but only slightly, especially with those tires and suspensions. And the downsides outweight the upsides... There's a reason why the 1930s is arguably called the "Golden Era of Grand Prix racing". There were several design breakthroughs that were, at times, so far ahead of the technology of the time, at times, we can be sure that they don't know the full extent of the potential of their designs! The cars were powerful and fast, and the tires became an extremely important consideration. Tires were a limiting factor to the performance of those machines. As we know, they were cross-ply design, and were pretty narrow. Now, we knew that that's not really ideal, but it is a combination of they don't really know that at the time, and the technology of the time could only allow them to do such. The tires also use canvas for its casings, and natural rubber. Synthetic rubber had been around by then, but it is still very new, and expensive to make, so it is ultimately not used on those racing tires. Thanks to the design and materials used, those tires were, consequently, pretty sensitive to heat, on fast tracks such as Mellaha (Tripoli) and AVUS, for example, it would be better if new tires were to be carefully run in before pushing, or else, they would literally disintegrate in just a few laps. But, I think it is very hard to be careful with new tires, considering that they had to deal with, at times, more than 400hp, and bags and bags of torque. The width of those tires means that there's not much lateral grip to get from them. An engineer friend of mine said that according to some sources, those cross-plies could only handle about 1g of cornering load before slipping. Also, thanks to the varied road surfaces of the track of the time, roadholding is a important thing to consider, and with all the bumpy and uneven surfaces, they tend to use soft suspensions (soft when compared to today's racing cars). The cars themselves were designed to slide around the corners, using the inherent lack of grip of the tires to, ironically, make it 'round the bends in the fastest way possible. So, okay, putting wings on them, I think, would cause the suspension to bottom out a lot, and also increase the grip, but not much. The one thing they might do, is to drastically increase heat buildup on those 1930s tires and make their life shorter. As a final thing, I think I would like to end with a piece I remembered reading somewhere. Eng. Robert Eberan-Eberhorst, the designer of the Auto Union Type D, later recalled that "if only they had those mid-1960s-era tires to fit in the D Type back then..."

[@WynnofThule]

What would help is if the tail were accompanied by shark fins. Side force doesn't strain the tires, it directly gets it's grip from the air itself.

[@flashpeter625]

The paradigm of grip was very different. It had almost more to do with motocross or flat track bikes than with today's cars. Lateral friction was not achievable. The suspension and the whole geometry with wild cambers was such that the car would be kinda trying to dig the tire into the surface to get forwards traction. Correctly stated that the surface of racetracks was nothing like today. It was either hard concrete, or it was very rough bitumen-bound rubbish, more like a glued gravel rather than asphalt as we know it now. On these softer surfaces, the narrow and hard tires got a good bite. It is almost like thrust pointing backwards, and angling it with the whole car.

That Type C, though - when I've mastered that car, I'll know I've learned Assetto Corsa.

It's so unforgiving of the slightest mistake...yet an absolute pleasure to drive when you're on your game.

[@jcgabriel1569]

That's the thing with the Auto Unions. They're not the easiest thing to drive. The driver sits so far in front, that it's very hard to gauge how much sideways you're getting. And with those cross-ply tires, it gets sideways so easily. Even back in the day, not many drivers could get their heads around it, only some of the most daring drivers of the time could really push them hard. One thing of note, though, some of the most successful pilots of the Auto Unions were Bernd Rosemeyer, Tazio Nuvolari, and Achille Varzi, all three of them were former motorcycle racers. That probably had something to do with it...

At 90mph you are definitely benefiting from the downforce. While testing on Miatas, difference between ones with and ones without wings was pretty big on tracks with average speeds under 80mph. Formula student cars usually don't even get close to 60mph and all competetive ones run extreme aero packages.

[@cademckee7276]

Formula student cars run such big wings and aero packages to make downforce at lower speeds. The lower the speed the more aggressive an aero package can be because you don’t have to worry about drag and yes downforce makes a difference even for slower cars, in a formula car you feel the downforce start to make a real difference around 70-75 mph, obviously the heavier the car and worse the aero thats gonna get higher but it still has a drastic effect on lap times

I noticed in the first lap, you were more or less guiding the car through the corner with the entire car. The second lap seemed like your steering input was more precise. I'm thinking for that track something more like a traditional F1 set up, or 60's/70's winglets and wing set up might have worked better. For several obvious reasons, all of which you have pretty much stated. But this was a very cool experiment. Very cool video.

[@Dan-vt9vk]

Wonderful video idea; it really makes you wonder why racecar designers didn't discover downforce sooner. My fave example: The Opel RAK rocket car program utilised simple wings, but primarily to keep the wheels on the ground at high speed. Most notable was the RAK 2, which reached 148 mph during a record run at AVUS in 1928 (only 60 mph off the land speed record at the time). A rocket-powered car with wings in the 1920s - it's still a futuristic idea 100 years later!

It would be interesting to see this car with wings attached directly to the unsprung mass, applying downforce to the wheels without causing any heave compression in the suspension.

[@jjracing4651]

Interesting experiment, would love to have seen the data for those laps! I know you doubted it's benefit in the first part of the lap, but I noted you were already 2-3 seconds up when you exited the corner with the pot-hole, so it seemed to have gained time fairly equally around the lap. I noted you were able to brake much later into the corners (almost trial braking style) and crucially, your accelerating out of every corner was much better! I know you will get the benefits of the downforce more at higher speeds (downforce is squared with speed essentially), but that extra mechanical weight certainly helped to grip up the wheels better! P.S. amazing introduction - the cinematics were lovely to look at!

Anyway, thank you!

[@julianbailey2749]

Did you change any of the car's setup except the wing? I thought that it would allow you to stiffen the suspension a bit that would help counter the top weight roll in those early bends without becoming too skittish on other parts of the track. Great video overall though, thanks for all your usual excellent output. Also 6 secs on a 3:30 minute lap isn't a small improvement, that's almost 2 secs a minute and would normally take years of development to achieve.

Your episodes are getting better and better and definitely crossing into the world of real racing history. But what you are leaving out was the Chaparral 2E had another innovation which cost its reliability and kept it from dominating the 1966 Can-Am season. Because of Jim Hall's connections at GM engineering as well as being an innovator, a decision was made to attempt to run an automatic transmission in the 2E, something that Chaparral continued to experiment with over the years. Without a whole lot of success... The price of being an innovator.. If they had run a standard gearbox, it is almost guaranteed the 2E would have dominated the series and downforce research and development would have accelerated that much quicker. Keep doing what you do, your series continues to improve and it is highly appreciated.

[@Villoresi]

Even with that transmission, the 2D won the Nurburgring in '66, and the 2F Brands Hatch in '67. It's still quite something to see the photos of the 2F at the '67 Targa Florio (incongruous to say the least).

Haha great video Jake. My thoughts are the height and weight of this wing would induce the car to be top heavy in fast corners. This would create more roll effectively lifting the inside wheels from the track and reducing overall grip. So sort of undoing what you were trying to do. I wonder if fitting a lower, lighter wing would have a different effect?

[@benjaminrogers9848]

This is an interesting point. Would the force from the wing help self center and offset the extra body roll? ie. The wings force points into the corner with more body roll

In updating the physics model, I didn't hear you mention drag. Just weight and downforce. Were you able to modify the drag function somehow to add wing drag into it? Seems not, because you actually hit a higher max speed with the wing than without it (162 with it, 160 without). I thought maybe your exit speed from the last corner might have been higher with the wing, but your speed under the bridge was 120mph in both cases - the same. This was really fun to watch.

Its interesting the Type-C and its rival the Mercedes W25 overtopped Fritz von Opel’s RAK rocket car run (238 kmph / 1928) which had mid-body inverted aero wings (negative lift) to keep it planted on the AVUS straight. It couldn’t make the banked turns as the rockets were fixed and the steering inputs were to keep the car straight over the bumps. I suspect because it wasn’t a wheel driven car, after its successful demonstration that project moved on to a rocket train and rocket aircraft, the focus of the racing teams may have been more on each other. Part of the trick was to get the wings over the axels, but the mid-body idea makes sense for a single wing set.

[@lingSpeed]

Very cool! :) I am thou skeptical of the modifications. The wing might look simple but it's still a result of many, many years of engineering. That thing produces massive downforce. With the amount of power the car has, and tightness of the track, drag means little. But just getting that much downforce in such a small package would not be as easy back then. Plus, knowing how AC does tyre load sensitivity, car in the video likely had a bit more grip than it would be possible with the tyres they had. If there is one thing studying both history and engineering taught me is that generally what we call today brilliant or revolutionary ideas were still just small increments back then. And engineers of old knew a lot more than it seems today. Most of them likely knew downforce would be good, but there would be many indirect reasons for the technology to adapt slowly. Also, when doing any reality check of car mods, downforce is the most common/biggest thing getting over exaggerated ;). Still, by virtue of "been there, done that" i appreciate the work that went into the video. Cheers!

How close the Germans were to discover the potential of downforce in the late 1930's? They actually discovered ground effect, and measured it in a windtunnel, but the engineers considered it a measuring error... The Auto-Union Type D slipstreamer for speed record runs was developed and prototyped in scale models to maximize stability, reduce lift, and minimize drag. One version in 1938 featured what we would call sideskirts today, and other unusually shaped body panels. This effectively sealed the floor and acted as a Venturi tunnel. They wanted more stability and less lift, and they accidentally got both through downforce. The model was measured in a windtunnel with zero lift. The rig was only set up to measure lift, not downforce. Rather than realizing that the measurement was correct, and that the model undid all of the natural lift and more, the measurement was seen as an error. At first look, they were not being too unreasonable - every single time before, they measured non-zero lift. Usually they struggled to keep the car on the ground at high speeds. Some models produced so much lift that they would take off, some would stay on the ground but unloading the wheels to varying extent, but no model ever produced downforce. Considering how brilliant and Germanly pedantic the engineers were, some of them with experience from airplane engineering, I would say that they were literally one shower-thought away from realizing what was actually going on with this model, measuring it again, and exploring it. This "accidental ground effect" version of the car was very stable in tests. And it had just a tiny but more drag than the conventional designs. So they made it in full scale and ran it in speed record attempts, without realizing what they were doing. That's the car Berndt Rosemeyer died in during a speed record run. Crosswind destabilized the car, some overloaded body panels probably sheared off, he could not catch the slide, and the car flew off the highway at a huge speed. The development of this version was discontinued. But in the midst of GP technical regulation changes between 1937 and 1938 (a switch from a maximum weight formula, to a minimum weight formula + engine displacement limit), and expected developments into the 1939 season (power-to-weight ratio was getting insane again), they had spare weight to play with. They actually considered running compact slipstreamers on some slower circuits. Porsche even submitted a viable design to Mercedes, you can find a blueprint scan under the name "Mercedes T90". With all of this, rather than strapping a wing on the car, they might have been pretty close to coming up with ground-effect slipstreamers. The next time ground effect was used, that time intentionally, was in 1960 on the insane Bluebird-Proteus CN7 land speed record vehicle, which is a story and a half in itself. And then Colin Chapman with Lotus 78, but that is a well-known history.

To my poor understanding, the wings were much more effective when the downforce was applied directly to the wheel hubs forcing the tires into heaver contact with the pavement, than when applied directly to the chassis. I claim no expertise in this manner, just seem to remember it by living through the early areo age and being fascinated by F1 and Can-Am race cars. Would you consider doing a follow up using a wing from a Chaparral?

[@egoalter1276]

A ground effevt streamlimed chassis exists for the tyle C (the ground effect was accidental), and it was used in a land speed record attempt. It likely couldnt compete with 70s f1 because of the cross ply tires and drum breaks wearing out too quickly, but for a single hotlap, maybe. These machines were basically a century ahead of their time, and are insanely impressive, but also very umrefined.

[@m2nesli]

what i wonder is .. is the wing placement are impacting on the car setup .. on this exemple the wing act like a front wing with majority of the downforce focusedd on the front tyre .. if you placed the wing at the back what would have changed ?? lighter direction ? more nimble? less bouncy ?? i would love to have your opinion. greetings from france.
